Cone degeneration (CD) is an inherited disease of the retina. Cone cells start to degenerate in the puppy-stage already, leading to a distinct form of dayblindness. Affected puppies avoid bright light, as those conditions can cause pain for the dog. Vision in dim light conditions or at night stays normal. First symptoms can be recognised at the age of about 8-12 weeks. Afterwards, symptoms increase as cone cell degeneration progresses over time.
